- Showcases 1 of 7 dinosaurs from the Cretaceous Period pictured on the souvenir sheet
Stamp Category: Commemorative
Value: 32¢, First Class Mail Rate

First Day City: Grand Junction, Colorado
Quantity Issued: 219,000,000
Printed by: Ashton-Potter (USA) Ltd.

Perforations: 11.1 x 11
Tagging: Two large tagging blocks, one over the top eight stamps and one over the bottom seven stamps. Tagging follows the odd shape of the perforations.
Why the stamp was issued: Issued in hopes of capturing the attention of young people with a subject they might find interesting.
About the stamp design: Stamp pictures artwork by James Gurney of Rhinebeck, New York (best known as the author and illustrator of the Dinotopia books).
First Day City: The World of Dinosaurs stamps were dedicated in a ceremony at the Museum of Western Colorado’s Dinosaur Valley Museum in Grand Junction, Colorado. Grand Junction is known as the “Dinosaur Triangle” of western Colorado and northeastern Utah. Many dinosaur fossils have been found in the area over the years.
Second Day Ceremony: The second-day ceremony was held on May 2nd at the Berger Dinosaur Hall of the Museum of the Rockies in Bozeman, Montana. Consultant Jack Horner was the main speaker. Horner’s famous long-time rival, Dr. Robert Bakker, had attended the first-day ceremony, making one wonder if, perhaps, Horner had decided not to attend in order to avoid him.
About the World of Dinosaurs set: Originally to be four stamps, Gurney was later asked to do eight designs, then 10, and finally 15. This was partially inspired by complaints USPS had received in the past about wasting paper on big souvenir sheets. Gurney arranged the dinosaurs in two panoramic shots, one representing the Jurassic Period (150 million years ago) and the other representing the Cretaceous (75 million years ago). The artist consulted with famous dinosaur expert Jack Horner as well as Michael Brett-Surman of the Smithsonian, Ken Carpenter of the Denver Museum of Natural History, and Phil Currie of the Royal Tyrell Museum of Paleontology in Alberta, Canada.
In addition to offering suggestions for less-common dinosaur species, Gurney said “The scientists also provided me with lots of information about other creatures that would have shared the world with dinosaurs: frogs, turtles, insects, crocodiles, pterosaurs, mammals, and birds – as well as the plants: sequoias, cycads, tree ferns, and horsetails… Recreating the full texture of this environment was very important to me. Too often, illustrations give the impression that dinosaurs just trotted around on dry lakebeds looking grumpy while a volcano chugged away in the background. In fact, their world was a rich and diverse ecosystem. There were plenty of plants and animals that looked a lot like what you would find today in Florida.”
History the stamp represents: Some of the strangest Cretaceous creatures were a group of dinosaurs known as hadrosaurs. Plant eaters with duckbilled snouts, these dinosaurs also sported unusual crests and helmets on top of their heads. One of the most remarkable of these crests belonged to Parasaurolophus.
Like other hadrosaurs, Parasaurolophus had powerful jaws lined with a spectacular array of diamond-shaped teeth which were used to grind the leaves of the conifer trees on which he fed. Believed to have attained a length of 30 to 33 feet and a weight of four to five tons, he walked upright on his hind legs, using his flat, broad tail to rest on while browsing. But the long, curved, bony tube which protruded back from his head set the Parasaurolophus apart.
When scientists cut the crest open, they discovered that it had several air passages connected to the nostrils. By forcing air through the passages, a bellowing noise was created, causing some scientists to believe this crest was used as a resonator to sound alarms and attract mates. Others have suggested that the crest served as a defense mechanism, allowing the Parasaurolophus to spray a heated, chemical vapor, much as a bombardier beetle does today.
